Replacing fuses
Expression and Insight facepanels have three fuses. Two are for AC input power and the
third is for the interface used by optional RFU and remote I/O devices. If the facepanel or
remote devices connected to it fail, first verify that power is available at the AC service outlet
and that all cables are properly connected and undamaged.
Express facepanels only have an External 12 Vdc fuse. This fuse is for the desk lights, the
RFU and any remote macro controller attached to the facepanel.
Always replace fuses with the same type of fuse. The AC Input fuses are type T6.3A . The
fuse protecting the RFU/Remote I/O circuits is type F1.6A (Express) or T2.5A (Expression/
Insight). Both types are slow action, 250V fuses. Replacement fuses of both types are
provided in the facepanel’s Spare Parts Kit, which is located beneath the face panel.
Replace AC Input fuses (Expression/Insight only):
N o t e :
These fuses are contained in a swiveling tray located between the power switch and the
power cord connector.
Step 1: Turn off the facepanel and disconnect the AC input cable.
Step 2: Pull the fuse tray out of its holder by pulling the small tab at the bottom of the tray
cover using a small tool, like a small flathead screwdriver or a small paperclip.
The tray remains connected to the tray holder but rotates downward for
convenience. Operate the tray carefully to avoid damage.
Step 3: Examine both fuses. Telltale signs of a blown fuse include discoloration or
deposits on the glass envelope and/or a visibly broken fuse strip.
Step 4: If you find a blown fuse, replace it with the fuse of the same type and size from
the facepanel’s Spare Parts Kit. To retrieve the Spare Parts Kit, see Open the
Facepanel, page 219 .
Step 5: With good fuses installed, rotate the tray up and inward until it is again flush with
the panel.
Step 6: Replace the power cord and check the facepanel for proper operation. If still
having problems, see Help from ETC Technical Services, page 3 .
Replace the External 12V / RFU / Remote I/O fuse:
N o t e :
This fuse is located in a pop-out receptacle located next to the RFU port on the
facepanel’s rear panel.
Step 1: Turn off the facepanel and disconnect the AC input cable.
Step 2: Remove the cover of the fuse receptacle with a flat blade screwdriver.
Step 3: Remove and examine the fuse. Telltale signs of a blown fuse include
discoloration or deposits on the glass envelope and/or a visibly broken fuse strip.
Step 4: If you find a blown fuse on an Expression or Insight facepanel, replace it with the
fuse of the same size and type from the facepanel’s Spare Parts Kit. To retrieve
the Spare Parts Kit, see Open the Facepanel, page 219 . If you have an Express
facepanel, make sure you use the same type of replacement fuse.
Step 5: With a good fuse installed, reinsert the fuse into the rear panel holder and secure
with the screwdriver.
Step 6: Verify that the external device works properly. If still having problems, see Help
from ETC Technical Services, page 3 .
